Oiler for derricks



NATHANIEL A. RIGGIN, OF QILFIELD3, CALIFOBIIIA.

OILER FOB DERRIOKS.

Application filed December 16, 1924.

To all whom it may concern:

Be it known tha l, NATHANIEL A. Rio- GIN, a citizen. of the United States, re'sidii'ig at Oilfields, in the county of Fresno and State of California, have invented a new and Useful Jiler for Derricks, of which the following is a specification.

This inventioi'i relates to oilers for saddles of the walking beam of an oil derrick and the object thereof is to provide a device of this character which will effectively oil the journals of the saddle and which is so constructed that access to said journals may be readily had.

Another object of the invention is to pro vide an oiler of this character in which the journals of the saddles are protected from dust, grit and the like and which aitords ready access to the journals for re rains and the like.

With the foregoing and other objects in view which will appear as the'description proceeds, the invention resides in the combination and arrangement of parts and in the details ot'construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

in the accompanying drawings Figure 1 represents a plan View of aportion of a. derrick walking beam with this improved oiler used in connection therewith, the cap at one side being removed to show the interior; a

Fig. 2 is a transverse section taken on the line 2+2 of Fig. 1;

' Fig. 3 is a section taken on the line 3-3 01:" Fig. 1; and j Fig. 4b is a detail perspective view of one of the removable shoes employed in this apparatus.

In the embodiment illustrated a derrick walking beam saddle 1 is shown having semi-circular journals 2 at its opposite ends which are mounted for rocking movement in correspondingly shaped bearings 3 which also are designed to operate as oil boxes to contain oil for lubricating the journals.

The journals 2 are equipped with remov- Serial No. 756,316.

able shoes 4; shaped to conform to the convex faces of the journals and provided at their ends with inwardly extending apertured fingers 5 which are counter sunk in the upper rectilinear faces of the journals and secured by fastening screws. .These shoes 4 being removable may be replaced when worn or broken with very little trouble.

The combined bearings and oil reservoirs 3 are provided with removable face plates 6 secured in oil-tightrelation to the reservoirs and which are designed to be removed to all'ord access to the journals of the beam so that if desired the shoes t may be removed without disturbing the beam proper, all that is necessary being to remove the oust caps 7 which are mounted over the journals as shown clearly in Figs. 2 and 3, remove plates 6 which will permit the screws which secure the shoes 4t in. place to be removed and permit the shoes to he slipped longitudinally or endwise of? the journals and others substituted therefor.

The dust caps 7 are constructed as shown in Figs. 2 and 3 being semi-circular or rather semi-cylindrical in cross section and provided at their side edges with longitudinally extending apertured flanges 8 which are bolted to the flanges 3 oil the journals. In the use of this oiler the journals 2 being mounted to turn in the combined oil reservoirsand bearings 3 said reservoirs are filled. with oil so that the rocking of the beam may be efi'ected without danger of the I 2. The combination of a supporting strucand conforming to the configuration thereture including oil reservoirs, said reservoirs 7 having curved inner surfaces, journals tted within the reservoirs, said journals being curved to cenfnrin t0 the shapes of the reservoirs, a curved shoe having imvnrdly e):- tendecl end portions fitted on each journal, su' l inwardly extended end portions having openings, securing members extending through the openings to secure. the shoe is its journal, and removable (lust cups for the 1ournals.
